I have a 3000 gallon pond that I normally top off using my well water. The
house is on city water, the well pump quit after 17 years and it is getting
replaced. I need to top off the pond with about 200 gallons of water.
Anyone else here ever buy a applicator for fertilizer that goes on the end
of hose , mix the appropriate amount of water and dechlorinater in the jug
and top off there pond? I am doing it as I write this, I actually put twice
the required amount of dechlorinator in the jug and put enough for 2500
gallons at the intake of the pump to spread it around. How do other people
deal with this when you use city water?


I do about that amount every day with city water, and haven't used dechlor
at all. On the few occasions I have done closer to a 50% change, I've used
it, just dumbed it in and proceeded to fill the pond. The fish have not
been bothered at all.
I would probably do it differently if I thought there were chloramines in
the water, but as far as I know, there aren't.
